UNITED STATES ROBERT LIDDELL, OF

TECUMSEH, NEBRASKA.

OIL-BURNER.

To all whom it may concern:

Be it known that I, ROBERT LIDDELL, a citizen of the United States,residing at Tecumseh, in the county of J ohnson and State of Nebraska,have invented new and useful Improvements in Oil-Burners, of which thefollowing is a specification.

This invention relates to improvements in hydrocarbon burners, such asare usually employed with heating and cooking stoves.

It has for its object the provision of a burner which may be adjusted tothe various dimensions of stoves now in use.

A further object is the provision of a burner in which the number ofparts are reduced to a minimum and so arranged that they can be readilytaken apart whenever desired for cleaning purposes.

With these and other objects in view, which will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims; it being understood that various changes inthe form, proportion, size, and minor details of the device may be made,within the scope of the appended claims, without departing from thespirit or sacrificing any of the advantages. of the inventionm In theacconipanyin drawings :Figure 1 is a vertical sectiona view of thedevice;

ig. 2is a sectional plan view on the line 2-2 of Fig. 1; Fig. 3 is avertical section of a modified form of the device; Fig. 4 is a sectionalplan view on the line 44 of gimilar numeralsof reference designatecorresponding arts throughout.

The device a out to be described, is shown applied to the body of anordinary heating stove and forming a part of the said body.

The pedestal or base of the stove is shown to include a circular plate 5supported by legs 6 and arranged on the plate 5 is the burner base 7.This member conforms substantially to the shape of an inverted frustumof a cone, its upper or widened end being provided with an outwardlyextending circular flange 8.

' The body of the stove is designated by the numeral 9 and iscylindrical in contour, having at its lower end an inwardly extendingcircular flange 10 which bears on the lower Specification of LettersPatent.

' face of the flange 8, the parts being secured together by means ofbolts 01' rivets 11 passing through the flanges.

The top plate of the body 9 is designated by the numeral 12 and issupported by the upper edge of the body and has an enlarged centralopening, the side of which is provided with a circular rabbet 13.

The central portion of the lower end of the burner base 7 is bulgedupwardly to provide a frnsto-conically shaped extension 14, the upperbase portion of which is interiorly thickened, as shown at 15, and screwthreaded so as to provide a threaded opening of uniform diameter. An oilinlet pipe is designated in general by the numeral 16 and has one endthreaded into the threaded portion of the extension 14, as shown in Fig.1.

Arranged in the space between the opposed faces of the base 7 andextension 14 and formed integral with the inner surface of the base 7are a plurality of vertically extending spaced ribs 17, the inner sidesof which are spaced from the adjacent surface of the extension 14 andthe upper and outer corners of which are rabbeted. The ribs support, inspaced relation to the lower end of the burner base 7, a htod creasing,the said hood or casing including a cylindrical body portion 18, thelower end of which terminates in a hollow and substantiallyhemispherically shaped: extension 19, the lower edge of said extensionbeingseated in the rabbets at the upper and outer corners of the ribs17. The upper end of the cylindrical ortion 18 is received by one end ofa simi arly shaped member 20, the opposite end of which isprovidedexteriorly with a circular cover 21, the periphery of which isbeted portion 13 of the top plate 12. \Vith this construction, it willbe manifest that the hood consists of telescoping sections, thusrenderin it adjustable to various heights of stoves. Zrranged in theupperend portion of the cylindrical extension 20 isa plate 22 having aplurality of spaced radial openings and pivotally mounted on the plate22 is a similar p ate 23 having openings to be moved into and out ofalinement with the openings in the plate 22. The top plate 12 isprovided adjacent to its outer periphery with a circular groove, andseated in this groove is an inverted dish-shaped covering 37 having a.plurality of openings 38. These openings together with the openings ofthe rabbeted and designed to bear in the rabplates 22 and 23 providepassages for the. air to pass into the hood to mix with the oil flowingfrom theinlet pipe 16.

In the operation'of the device, thus far described, a quantity of oil ispermitted to flow from the inlet pipe 16 to the bottom of the base 7.The oil is then ignited, this operation being performed by opening thedoor 24 in the side wall of the burner base 7. The burning oil heats theburner base 7 and also the hemispherical extension 19. After the greaterpart of the oil is consumed and the extension 19 is heated to therequired degree, the valve (not shown) in the oil supply pipe is openedto permit a proper quantity of oil to flow through the pipe 16. The oilpassing through the pipe 16 is vaporized by the heat of the conicalextension 14 and hemispherical extension 19 and mixes with the airpassing downwardly through the cylindrical extensions 18 and 20. Thiscombined mixture of gas and air, when ignited, will further heat thesurfaces of the extensions 145 and 19. the products of combustionpassing upwardly and over the outer face of the hemispherical extension19 into the space between the casing and hood, and thence through anopening (not shown) in the rear of the casing, to the chimney.

In the modified form illustrated in Figs. 3 and 4, the burner base isdesignated by the numeral 25 and conforms to the shape of an lnvertedrustum of a cone, having at its upper or larger end an outwardly.extending circular flange 26. The cylindrical body of the stove isdesignated by the numeral 27 and is provided at its lower end with aninwardly extending flange 28 which is bolted or otherwise secured to theinner face ofthe flange 26. The central portion ofthelower end of theburner base 25 is bulged upwardly so as to provide a frusto-conicallyshaped extension 29 having at its upper end a vertically extendingcylindrical extension 30. An oil supply pipe is designated by thenumeral 31 and leads upwardly through the frusto-conically shapedextension 29 and is provided at its upper end with a T-shaped burnertip, designated by the numeral 32. The opposite horizontal portions ofthe tip 32 are received by oppositely disposed sockets in the upper endof the cylindrical extension 30 and the extremitals of the horizontalarms are curved downwardly, as shown at 33. With this construction itwill be seen that a space is provided on opposite sides of thehorizontal extensions of the tip for air which passes upwardlyand'through the extension 29. Arranged .in the space between theextension 29 and inner face of the side wall of the burner base 25 are aplurality of vertical ribs 34 similar to the ribs 17, and the upper andinner-corners of which are rabbeted. An inverted cupshaped cap isdesignated by the numeral 35 and houses the burner tip with its lower.

ference in the two structures residing in the admission of air to theburner base.

Fromvthe foregoing, it will be .seen that I have provided a device whichis comparatively simple in structure, and inexpensive to manufacture,the parts being so arranged that a maximum amount of heating surface islocated at the burner to promote the rapid vaporizationof the oil.
